dc.description.abstract We extended the standard model with a fourth generation of fermions to explain the discrepancy in the muon magnetic moment and to describe the positron excess observed by AMS-02 experiment. We introduce a gauged SU(2)HV horizontal symmetry between the muon and the 4th generation lepton families and identified the 4th generation right-handed neutrino as the dark matter with mass ∼700 GeV. The dark matter annihilates through SU(2)HV gauge boson into final states (μ+μ−) and (νcμ νμ). The SU(2)HV gauge boson with mass ∼1.4 TeV gives the required contribution to the muon (g−2) and satisfy the experimental constraint from BNL measurement. en_US
